As shown in fig. 1, a method for controlling CPU expansion based on a mobile terminal includes the following steps:
step S100, a first mobile terminal set as an active terminal and a second mobile terminal set as a passive terminal are in communication connection in a wired or wireless mode.
In the embodiment of the present invention, the first mobile terminal and the second mobile terminal have the same CPU architecture, and the present invention is preferably a 4-core CPU (of course, the first mobile terminal and the second mobile terminal may also be 2, 6, or 8 cores); the wired mode comprises USB connection, the wireless mode comprises WLAN connection or Bluetooth connection, and the connection mode can be other effective connection modes.

and S102, the active terminal and the passive terminal are in communication connection in a wired or wireless mode.
Step S200, any core CPU in the active terminal and the passive terminal is set as a scheduling CPU in advance to perform instruction scheduling, and the active terminal sends an instruction for starting the CPU to expand the active driving component to the passive terminal.
In the embodiment of the invention, 1 CPU is stripped as a scheduling unit for an active terminal, and the active scheduling unit is specially responsible for monitoring communication information from a CPU extension drive passive mode in a connection mode opposite terminal and for assembling a cross-terminal instruction set and scheduling a virtual CPU. And (3) stripping 1 CPU as a scheduling unit for the passive terminal, wherein the passive scheduling unit is specially responsible for monitoring communication information from a CPU extension driving active mode in a connection mode opposite terminal and for scheduling the CPU from the active mode to be converted into local.
When the running and processing capacity of the CPU of the active terminal needs to be improved, the number of the CPU kernels of the active terminal needs to be increased, and then the active terminal can send a command for starting the CPU to expand the active driving component to the passive terminal to control the passive terminal to run the virtual CPU.
Specifically, step S200 specifically includes the following steps:
s201, setting any core CPU of 4-core CPUs in the active terminal as an active scheduling CPU in advance, and setting any core CPU of 4-core CPUs in the passive terminal as a passive scheduling CPU;

s203, the passive terminal receives the instruction of starting the CPU to expand the active driving component through the passive scheduling CPU.
Step S300, after the passive terminal receives and executes the instruction for starting the CPU to expand the active driving component, the CPU expansion passive mode is completed, and the active terminal is accessed to a plurality of virtual application layer CPUs expanded by the passive terminal.
In the embodiment of the invention, the passive terminal executes the instruction for starting the CPU expansion active drive component, reserves a kernel drive level Linux core component, closes an Android system, completes a CPU expansion passive mode, virtualizes 3 application layer CPUs, accesses the 3 virtual application layer CPUs expanded by the passive terminal, completes a CPU expansion active mode, and controls the active terminal to be switched to a 6-core CPU, so that processes running in an application layer of the active terminal can have an arithmetic capability equal to 6 cores, and can be expanded to 8 cores (without a scheduling unit) at most, but the performance may not be as high as that of 6 cores (virtual) in the last step.
